DEVICE FOR TURNING THE PRIMARY FOLDS FOR HEMS.

Specification of Letters Patent.

Patented Jan. 28, 1908.

Application filed October 4, 1906- Serial No. 337.393-

T all whom it may concern:

Be it known that I, DANIEL MAUS, a citizen of the United States, residing at WVorcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Device for Turning the Primary Fold for Hems, of which the following is a specification.

The object of this invention is to provide a new and improved mechanism by which a strip of cloth can have the edge thereof folded over so that the strip can be drawn forward by a hem-stitching sewing machine, whereby the cloth can be fed automatically.

The device is illustrated in the accompanying drawings, referring to which, Figure 1 is a side elevation of the preferred form of the mechanism. Fig. 2 is a plan view. Figs. 3 and 4 are diagrammatic views inserted for the purpose of explanation. Fig. 5 is a perspective view of the apparatus, the cloth being indicated in dotted lines. Fig. 6 is a detail illustrating part of one of the folders. Fig. 7 is a detail view of the mechanism for holding the compressing wire in place. Fig. 8 is a plan View of the folder. Fig. 9 is a cross sectional view thereof taken on the line 99 of Fig. 8, and Figs. 10 and 11 are detail views of the adjustable spring clips for guiding the cloth.

The customary practice in making garments and similar articles is to cut cloth into long strips and to feed the same through sewing machines which will hem or tuck such long strips. The customary way to form a hem is to turn the cloth 0 over as at d, as shown in Fig. 8, to form a primary fold, then to turn the edge of the cloth in at 6, Fig. 4, to form a secondary fold, and then to stitch through the three thicknesses of cloth to secure the hem.

In hem-stitching sewing machines, as now constructed, the operator turns the cloth over on the primary fold as indicated at Fig. 3, and feeds the cloth to the sewing machine in this condition, the sewing machine turning over the secondary fold and stitching the three thicknesses together. This operation necessarily requires an operator for each sewing machine, and makes the operation dependent upon the dexterity and manipulation of the operator.

The object of this invention is to provide a device by which the edge of the cloth can be turned over for the primary fold, as it is drawn forward to the sewing machine, so

that the cloth will be automatically manipulated, and so that an attendant for the sewing machine is not necessary. By this arrangement one operator can attend to a large number of machines, and long strips of cloth, say fifty or eighty yards, can be automatically drawn through the machine and hemmed.

. To carry out the invention in an operative way it is necessary that the primary fold should be very accurately made. To do this, I have provided a frame over which the cloth is drawn, which frame has a primary creasing device which will form a crease or breaking line in the cloth, and a folder or funnel which will fold the cloth accurately on the line which the creaser has made. The parts are preferably arranged so that thecloth asses down over the primary creaser to the 'older. The parts are also arranged so that the device 1s adjustable for various widths of cloth. By using an attachment of this nature I have found that the purpose above stated can be admirably carried out.

The details of the apparatus will be best understood by a specific description of the parts.

Referring to the drawings and in detail, 10 designates a rear, and 11 a front support, each of which consists of a rod vertically arranged in a suitable support. Fitted on the rod 10 is a bracket 12 which is held in vertically adjusted position by a screw 13. A rod 14 is passed through a hole bored horizontally in the bracket 12 and is held in adjusted position therein by a screw 15. Adjustably snapped on the horizontal rod 14 are two spring clips S, the detail construction of which is hereinafter described. Secured on the vertical support 10 is another bracket, and fitted in the horizontal hole of the same is the horizontal arm of the primary creaser P. This primary crearer consists of a piece of wire or of a rod, which is bent up at the angle as shown, and the end of which is flattened out to have a disk-shaped end which is comparatively thin and which is rounded. The cloth is led up over the horizontal rod 14, and then is passed down over the end of the primary creaser P. This will act to put a sharp fold or creased line in the cloth, as shown more par ticularly in Figs. 1 and 2.

Arranged on the front vertical support 11 at a lower level than those on the rear supports are two more brackets 12-.12. The lower bracket carrier a horizontal arm 18 which-is offset upwards, and to Which the folder F is secured at a lower level than the primary creaser. This folder consists of an external turner or funnel-shaped piece 19,

i the external turner 19.

and an internal turner 20 which is formed from a loop of metal, the internal turner 20 being soldered to an arm 21 extending from These parts are arranged so that as the cloth which has been creased by the primary creaser is drawn in between the external and internal turners, the edge of the cloth will be accurately folded over on the body of the cloth along the crease which has been made by the primary creaser. A spring clip S is snapped onto the arm 21 extending from the external turner to which the internal turner is secured to keep the cloth accurately in the folder. A rod 22 is secured in the upper bracket 12 arranged on the front support 11. A collar 23 is fitted on this rod, the hole through the same being eccentrically bored. The collar is kept in place on the rod 22 by a screw 24. A wire 25 is fastened in the collar 23, and bears on the cloth just before the same passes into the folder F. This wire 25 is bent or sprung so as to bear with a spring tension on the cloth, and the degree of this tension can be adjusted by turning and setting the collar 23 on the rod 22.

A spring clip S is snapped on the rod 22 to guide the main portion of the cloth accurately with res ect to the folder. I11 addition to the sing e clip S, three spring clips S are used as previously pointed out, two being placed on the horizontal rod 14, and one on thehorizontal rod 22. By adjusting these spring clips, the strip of cloth can be made to run very accurately through the apparatus, and the apparatus may be adjusted to fold various widths of strips. One of these spring clips S is detailed in Fig. 10. The same will be seen to consist of a wire which is bent to form a loop 26, the end of which extends through the two legs 2727. The ends of the two legs are connected together by a piece of metal 28 which is soldered or secured thereto. The loop and the legs 27-27 are bent to form circles 29-29 which area little smaller in diameter than the diameter of the horizontal-rod on which the clip is to be placed. The two strands of wire are bent to form spring loops 3030, so that the circles 2929 will normally tend to contract. By this arrangement, by pinching the loop 26 and the two legs 2727 together, the circles 2929will be opened so that the clip can be placed on and slid back and forth, and adjusted on its rod. I/Vhen the parts are released, the clip will tightly clamp the rod to retain its adjusted position. By this arrangement, the operator can quickly set the clips, as the manipulation of screws or clamping means is not necessary.

The clip S used in connection with the internal turner is shown in detail in Fig. 11. The same consists of a wire bent to have a spring coil 31, legs 32-32, coils 3333, crossing arms 3434, which have hooks 3535 at their ends. These hooks are adapted to engage the arm 21 so that the spring-clip S can be quickly adjusted thereon.

By the arrangement described 'it will be seen that a simple and neat apparatus is provided for the purpose stated, and one in which the small adjustments necessary to get the cloth running accurately can be quickly made, and also a device in which considerable adjustment is allowed so that the apparatus can be made to fold strips of cloth of different widths.

The details and arrangements herein shown and described may be greatly varied by a skilled mechanic without departing from the scope of my invention as expressed in the claims.
